I'm trying to add content into the head tags of my handlebars layout but haven't figured out a way to make it work. Basically I just want to be able to add links to stylesheets or javascript files on particular pages, not site-wide. I've tried working with helpers and partials but nothing has worked so far, I think part of the problem is because most suggestions are for regular handlebars and they don't work quite right with express handlebars.
Should I use multiple layouts?
What I'm trying to do - layout.handlebars:
<!DOCTYPE html>
<head>
<title>{{title}}</title>
<link rel="stylesheet" href="/css/site-wide-styles.css">
{{css/js/meta unique to the page being viewed}}
</head>
<body>
{{{body}}}
</body>
</html>
